Good morning,
For the latest information with the QWC development, please join one of our Telegram channels.
General information:
https://t.me/qwertycoin | Support channel:
https://t.me/qwc_supportWe’re happy to announce that the network issues faced by Qwertycoin over the past couple of days are nearly completely resolved.
The team advises all users and miners to refrain from sending coins with any wallet until we announce the rollout of the new wallet software for Mac, Windows & Linux.
At present time, please
point all miners to the official Qwertycoin mining pool:https://qwertycoin.siteThis pool, and only this pool, are currently operational on the new Qwertycoin main net.
Please see below for an event timeline of the issues faced in the past few days and the steps taken by the Qwertycoin team to resolve them.
Issue #1: Blockchain Network Instability — Circumstance:
Users with old wallet and daemon (nodes or pools) creating valid blocks, which is not a part of main QWC blockchain.
— Cause:
They did not follow up on software updates.
— Result:
Transactions with question marks, unsearchable hashes, orphan blocks. Coins Vanished.
— Resolution:
The Qwertycoin team worked to resolve the initial updates with 2.0.0, but found that issues persisted.
This analysis brought us to the notion of an attack on the Qwertycoin network.
Issue #2: Blockchain Network Instability (Network Attack) — Circumstance:
Pool started to slow down and could not find blocks, leading to delayed payments, pool server log file size increased too fast too big. CPU load near max. so as in most working nodes.
— Cause:
High hashing power joined QWC official mining pool, solving time was way too quick. Log file size maxing out the storage limit of the server. nearly 215GB.
— Result:
Orphan blocks (two miners produce blocks at similar times due to high hashrate). Coins Vanished.
— Resolution:
The Qwertycoin team purchased and built up a brand new server with ample resources to mitigate the pending attacks. A brand new infrastructure was set up to support the pool, explorer, two nodes as well as protection and redundancy.
A hard fork at block height 46,000 was introduced to fix the issues from the attack originally on the QWC network, although we were quick to realise and act on the fork providing a further issue with rogue pools.
Issue #3: Blockchain Split — Circumstance:
Mining pools that were not updated to the latest version in time began acting rogue and sending invalid payments on a split blockchain. The official chain then grew out of sync due to the hostile takeover and being flooded again.
— Cause:
Higher hashrate on the 3rd partly pool along with their delay in upgrading the pool software and resetting statistics caused for a split in the main net, thereby affecting users mining on this pool and any transactions sent out.
— Result:
Coins there were paid by the 3rd party pool rendered orphan and cannot be verified by the main blockchain. We attempted to work off a snapshot from the 3rd party pool, although hit a corruption at block height 46,031.
The corruption meant that a final reset was needed on the network which introduced a new network identifier as well as advanced features towards the Qwertycoin software suite:
1. Nodes and Daemons that have not updated to the newest version of the main blockchain are redundant and do not exist on the current Qwertycoin network.
2. Wallets and nodes will no longer operate if the software is not up to date in the newest version of the blockchain.
3. The team worked directly with Zawy to include v3 of the difficulty algorithm, which from thorough testing is proving to be the best and most reactive difficulty algorithm for QWC yet.
This new version of the algorithm also works to defend against high hash rate attacks on the network, by adjusting quickly to any exponential increase in network traffic.
The new Qwertycoin Network has been running for close to 24 hours now with no issues faced by the old network. The team is currently thoroughly testing the new wallets and software prior to a release announcement.
An important note:It is critical that you maintain your Qwertycoin software and keep with the current updates to avoid the likelihood of issues like this starting again.

https://t.me/qwc_supportFor miners:At present time, please point all miners to the official Qwertycoin mining pool:
https://qwertycoin.site | This pool and only this pool are officially associated to the Qwertycoin Network.
No endorsement of third party services is implied. Use at your own risk.
In the event of forks or other network issues be sure any service you use is properly updated and supporting the correct chain.
Final note:We’re working hard to release the newest software for you all as soon as physically possible.
All coins that are mined and rewarded within the official pool WILL be reflect on the new wallet software.
We need your help to get the pool hash rate up to get the Qwertycoin Network back to the growing entity it was before.
As always, please don’t hesitate to reach out to us with support questions in the appropriate channel.
If you have any further notes or comments, please let us know in the General Information channel.
Thank you all for your patience and understanding during this time.
We look forward to working with you all to make Qwertycoin the success it should be.
Regards,
The Qwertycoin Team.
